PythagoraSwitch (ピタゴラスイッチ Pitagora Suitchi) is a 15-minute Japanese educational television program that has been aired by NHK since April 9, 2002. It encourages augmenting children's "way of thinking" under the supervision of Masahiko Satō (佐藤雅彦) and Masumi Uchino (内野真澄). A five-minute format called PythagoraSwitch Mini is also available.
During the beginning and ending of each episode, and between each corner (segment), there are Pythagorean Devices (ピタゴラ装置 Pitagora Sōchi). Pythagorean Devices are known in the U.S. as "Rube Goldberg machines" and in Britain as "Heath Robinson" contraptions. The main focus of the program is a puppet show, but the subject is mainly advanced by the small corners. World phenomena, principles, characteristics, and the like are introduced in an entertaining way. At the end of each segment "Pitagora Suitchi" is sung as a kind of punchline.
In the show, segments are called "corners".
A puppet show in which Grandpa Encyclopedia (百科おじさん Hyakka Oji-san) explains the structure of the world to the young penguins Pita and Gora. A recurring situation is that, while discussing each topic, Encyclopedia would often say "The details are on my Nth page", to what the Penguins, after looking said page, respond "We're children, so we can't read..." After that, the three call upon Televi-John (テレビのジョン Terebi no Jon) an anthropomorphic dog-like TV, who shows them a video about the topic. A mouse called Suu is also featured.
Pythagora Devices (ピタゴラ装置 Pitagora Souchi) are frequently featured.
A corner broadcast since 2002. It stars the duo Itsumo Kokokara. It is algorithm themed, so that the movements that are done side by side are related ("crouching motion" combines with "shaking arms", so that the arms avoid the action, etc.). Usually, the duo does the exercise with special guests, such as NHK announcers, baseball players, sumo wrestlers, etc.
There are also individual versions for each member: the "Yamada version" and the "Kikuchi version".
